Premarket evidence — what FDA accepted
source quote (p.4)
“The SIGNAT™ Artist Evo system is a whole body magnetic resonance scanner designed to support high resolution, high signal-to-noise ratio, and short scan times.”
source quote (p.4)
“The system can image in the sagittal, coronal, axial, oblique, and double oblique planes, using various pulse sequences and reconstruction algorithms.”
